Hello André,

If I understand well, the function you request is already available.

Ref GM4 documentation section "10.2 Undiverting output".
It states "As a GNU extension, diversions may contain non-numeric 
strings, which are treated as the names of files to copy into the output 
without expansion. A warning is issued if a file could not be opened."

In short, you divert as usual, into one or several divnum.  Then after 
you undivert into your specific files.

Regards,

Denis/
